1 .ication filed July 15, 1914;.

To all whom. it may concern:

Be it known that I, HnNnY N. ldiiLmn, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Fuseclip's, of which the following is a specification.

This invention relates to the construction of those fuse clips which are provided for 7 of the clips with which they are connected,

the elasticity of the clip fingers. If the elasticity is destroyed the clips are liable to become more or less bent and stay bent when a fuse is inserted or removed and this increases the objectionable factorof improper contact and consequent heating.

The object of this invention is to construct a simple and cheap terminal clip which'has great flexibility, and the contact surfaces of which'areself aliningand the springportions are so distant from the contact surfacesthat they will not become heated and loseth'e'ir elasticity.

Figure l of the accompanying drawings shows a plan offa fuse block with a pair of fuse clips which embody the invention Fig. ,3 shows a secticnpn'plane indicated by dot- Fig. 2 shows aside view of the same.

The clip illustrated has a base 1 which is v desirably a brass casting that at one end has awire terminal clamp' Q and l atthe other end has four upwardly extendingposts 3. p

sitely to each other between the posts.

Each of the plates shown is fastened to the inner end of a stud 5 that hasits outer end .held by the upper end of an upwardly extending spring plate (5. The studs pass between and are loosely retained'in position by the posts,- and the spring plates are fastened to the base of the clip by the screw 7 and nut 8. Current is conveyed to the con-- tact plates by a plural number of thin sheet metal leaves 9, the upper ends of which are held between the studs and the backs of the contact plates while the lower ends are clamped; between the lower ends of the spring plates and the base of the clip. The clips are mounted on an ordinary insulating block 10. 1

With this construction the contact plates are free to aline themselves with and fit flatly against the side of the'fuse tesminals that are forced between them. The spring of the contact plates, and the spring plates are so far from the'contact plates that they are not liable to become heated and lose their elasticity even should the contact plates fail to make close contact with the fuse 'terminals. Current is chiefly conduct-- ed to the contact plates b leaves which are made su cien'tly large to carry the requisite amount of current'and yet are so thin that they do not odor any material resistance to the self alinement of the contact plates when fuse terminals are forced between them.

lhe invention claimed is:

1. A fuse clip having a conducting base,

I spring plates with their lower ends fastened to the base, a pair of contact plates, conducting studs extending from the middle of the backs of the contact plates at right angles thereto to the upper ends of the spring plates, and means projecting from the base for loosely retaining said studs.

2. A fuse clip having a conducting base, spring plates fastened to and extending upwardly from the base, a pair of contact plates, means extending from the middle of the backs of the'contact plates" to the upper the conducting ends of the spring plates, and conducting means connecting the contact plates with the basei 3. A. fuse clip having a conducting base, spring plates extending upwardly from the base, a pair of contact plates, studs connecting the contact plates with the upper ends ofthe spring plates, and conducting leaves connecting the contact plates with the base.

l. A fuse clip having a conducting base, spring plates with their lower ends clamped to the base, a pair of eontact plates. studs connectedat their inner ends with the center of the contact plates and at their outer ends With spring plates, and conducting leaves extending from the middle of the eontaet plates to the base.

5. A fuse clip having a conducting base,

the spring plates, and conducting leaves with their upper ends held between the studs and the Contact plates, and their lower ends fastened between the base and the lewer ends of the spring plates.

6. A fuse clip having aconducting base with a wire terminal clamp and upright fposts, conducting studs loosely retained by said pests, spring plates with their lower ends fastened to the base and their upper ends engaging the outer ends of the studs, contact plates attached to the inner ends of the studs, and conductors extending from the Contact plates to the base.
